I have a 1997 Buick Riviera and I plan on getting a Rockford Fosgate sound system. A RF T2500.1bdcp and 2 RF T2's, I had 2 T1's and a T1500.1bd amp and the lights would dim like CRAZY!! And the rpm's dropped low as well. Now my question is what can I do to stop the lights from dimming so much. I have a 4 gauge wire going from my alternator to the jump post under the hood, but the lights still dim. And I have a extra car battery in the trunk. I want to get a high output alternator and a Kinetik Battery but idk if that'll stop the lights from dimming so bad. Also the sounds made my rpm's drop so low that it made my car stall out. PLEASE LEAVE YOUR OPINIONS AND COMMENTS, YOUR INPUTS ARE VERY APPRECIATED THANK YOU
